In the low temperature resistance experiment at -40 ℃, the sealing strip remained unchanged in hardness and did not become brittle, while still maintaining softness and good adhesion, demonstrating excellent cold resistance performance. At a high temperature of 120 ℃, the weather resistance of the sealing strip remains good, maintaining its elastic properties, and its shape and function are not affected.
The selection of sealing material determines its permanent softness and elasticity. By adjusting the formula, the softness of the dried sealant is improved, forming a good sealing layer between the sheet metal and the rubber strip. The unique high elasticity of butyl rubber ensures that the sealant is easy to peel off from the metal sheet metal without contaminating the sheet metal.
Automotive sealing strips are mainly made of EPDM rubber with good elasticity and resistance to compression deformation, aging, ozone, chemical action, and a wide temperature range (-40 ℃~+120 ℃), which is foamed and densely compounded. It contains unique metal fixtures and tongue shaped buckles, which are sturdy and durable, and easy to install.
